WELL-BORING MACHINE.

SPECIFICATION forming part of Letters Patent No. 398,211, dated February 19, 1889.

Application iiled July 7, 1887. Serial No. 243,614. (No model.)

T0 all whom it may concern:

Be it known that I, SAMUEL ADAMS, a citizen of the United States of America, residing at Beaver, inthe county of Beaver and State of Pennsylvania, have invented certain new and useful Improvements in fell-Boring Maehines, of which the following is a specification.

My invention has relation to improvements in machines for drilling holes in the earth, and the object is to simplify and improve existing machines of the kind or class 5 and my invention therefore consists in the novel oonstruction of parts and their combination, as will loe hereinafter fully specified, and especially as the same is particularly pointed out and distinctly claimed.

I have fully illustrated my improved machine in the accompanying drawings, where- 1n Figure l is a side view in elevation showing the machine mounted on a carriage for transportation. Eig. 2 is a top plan view; and Fig. 3 is a sectional view taken on the line o0 of Fig. l, the upper part of the machine being' broken off.

Reference being had to the ,lrawings, A designates a substantial frame, composed of stout side pieces on which the bearings for the different shafts are mounted, and connected by the cross-pieces c' c2 at the respective ends, and fixed lengthwise in the frame is a sill, A', substantially as seen in the drawings. This frame, for the purposes of transportation, may be mounted on the axles B', carried by the wheels B, as shown in Fig. l of the drawings. To each cross-piece of the frame is rigidly fixed a sleeve, C, in which the lower part of the upright standards pass through the sleeves, and may have their ends set in the ground to give them rigidity and stability when the machine is in operation, and at the same time hold the frame firmly in operative position. On the top of the uprights is detachably secured a top sill or cross-piece, D, which holds the standards from spreading and inward movement. Mounted in bearings near the top of each upright are the sheave-pulleys I I', which take the drill rope or cable. Mounted in bearings 1c on the side pieces of the frame is the bull-wheel or drum K, which has one end of the drill-rope i fixed thereto, and about which the drill-rope winds, or from which the drill-rope is paid out. The drill-rope is carried from this drum K upward over the sheave I', thence across in horizontal direction and over the sheave I, from which the end depends, and is attached to the eye of the drill. (Not shown.) The weight of the drill holds this cable taut and the part between the sheaves straight, so that when this part is drawn down from horizontality by any force the drill will be lifted, and when the force is removed the drill will drop by gravity and strike its work. To effect the reciprocation of the drill in operation, I mount in bearings l 2 on the frame an axle, 3, and x thereto a crank-arm, 4, and attach to the crank a cable, J, on the upper end of which is connected a sheave, j, arranged on the crossing line of the drill-rope, as shown. On the axle 3 is mounted a band-wheel, H, about which a belt, 5, is arranged, which communieates any suitable power. (Not deemed necessary to be shown.) On the axle 3 is a grooved pulley, 6, on which is loosely arranged a band or line, k', arranged, also, over the grooved pulley 7, fixed on the bull-wheel, substantially as shown in Fig. 2 of the drawings.

When it is desired to draw up the drill, by Simply applying pressure by the hand or an idler (not shown) on the band Zo', the bullwheel is turned and the drill-rope wound up and the drill lifted. To hold the bull-wheel against rotation, a disk, z', is fixed on its shaft, and about this is a. locking-strap, l. This lockingstrap has one end fixed in the cross piece of the frame, as at S, and the other end is attached to a lever-bar, Z', so that by raising or lowering the lever the strap is made tight or loosened on the circumferential face of the disk, and the bull-wheel thus held against rotation or left free to rotate and pay out or take up the drill-rope.

On the frame I mount an axle, 9, having a small drum, l0, thereon, and to this is fixed one end of the sand-pump line 2", which is carried upward and arranged on a sheave,.Z2, journaled to the upright C', substantially as shown, the line from the sheave depending and having attached to its end the sandpump L.

One end of the shaft 9 has its bearing in a post, d, pivoted to the frame at b, to the up IOO per-end of which is pvoted a rod, E, having pivotal connections to the hand-lever F, piv oted to the frame at j'. 0n the axle t) is: mounted a friction-pulley, G, which engages, l when so desired, with thc face of the band Wheel lvl. :ly this eonueetion and arrangen ment it will be perceived that the sandpnmp will drop hy gravity, and when iti is necessary i'o lil't the sand-pump the lever l" g. is drawn so as to bring the face ol the tricl tion-pulley in Contact with the face olf the band-wheel ll, the vtwo being held in Wilmot, and thus the pulley G rotated and the snndpump rope wound on the axle.

The operation oli' my machine is as follows: The iframe with vits mechai'iisin being' set iu position, the drill is attached to the drill-rope and motion communicated tio the l' a1i lwlieel g H, which turns a crank-arm, which drawsd own on the drill-rope and lifts the drill. .Yhen the crank is raised, the strain on the line]l is removed and the drill drops by gravity and i strikes its blow. lVhen it is desired to bring` Jthe sand-pump into requisition, the frictionf strap is released, the hand 7U" tightened, and l the drill lifted. The sand-pump is then inl sorted in the hole and runs down hy `gravity, and then raised by bringing the wheel G in contact with the band-wheel ll through the 'force of the lever F.

lVhat I ela-iin isM The Combination, with the frame A, havingI vertical end standards, C C', the wheel K, mounted on the frame, and the drixf'e-wheel H, provided with a crank-arm, of the sheaves lI and l', pivotally mounted on the respective end standards of the frame, the cable/i, aneliored to the wheel K and carried over the sheave on the standard at the opposite end ot' `fthe trame, thence carried horizontally between the standards and over the sheave I,

l and the cable il, provided with a sheave on its upper end to run on the drill-cable and having,` its lower end con nected to the crank of the drive-wheel, substantially as described. In testimony wh ereof l. atiix my si gnature in presence. of two witnesses.
